Rails コンソールからデータベースに値を挿入しようとしていますが、うまくいきません。
最初のコマンドは
u=users.create(:name="bob",:address="Dublin") です
これは、最初のコマンドを実行した後の出力です
u=Users.create(:name=>"Ben",:address=>"Dublin")
(0.2ms) BEGIN
SQL (0.3ms) INSERT INTO `users` (`address`, `created_at`, `email`, `name`, `password`, `updated_at`) VALUES ('Dublin', '2012-04-16 23:15:48', NULL, 'Ben', NULL, '2012-04-16 23:15:48')
(9.1ms) COMMIT
=> #<Users id: 2, name: "Ben", password: nil, email: nil, address: "Dublin", created_at: "2012-04-16 23:15:48", updated_at: "2012-04-16 23:15:48">
これは 2 番目のコマンドです
t=tweets.create(:status="I am a tweet from bob",:user=>u)
NameError: undefined local variable or method `tweets' for main:Object
